Abstract

Objective: The aim of this study was to develop and validate analytical methods for determining methamphetamine in saliva using gas chromatographytandem
mass spectrometry (MS).
Methods: The chromatography conditions were DB MS-5 capillary columns with a length of 30 m, inner diameter of 0.25 mm, mobile phase of Helium
gas 99.999%, flow rate of 0.8 mL/min, detection of MS at m/z values of 58.00 and 91.00, respectively, and ephedrine HCl as the internal standard.
Results: The validation of analytical methods for methamphetamine satisfies the validation criteria by the EMEA Guidelines 2011. Bioanalytical
methods obtained were linear in the concentration range from 15.0 to 300.0 ng/mL with r>0.9999. Sample preparation was done using liquid–liquid
microextraction with cyclohexane, supernatant residue was dried and reconstituted with approximately 100 μL of methanol.
Conclusion: The method was successfully applied to saliva samples of methamphetamine users with levels in the range of test.
